Answer:
<h2>Yes</h2>
Step-by-step explanation:
The formula of a distance between two points:
ΔABC:
A(2, 5), B(5, 5), C(5, 9)
ΔDEF:
D(-7, 8), E(-4, 8), F(-4, 4)
AB ≅ DE
AC ≅ DF
BC ≅ EF
Therefore ΔABC ≅ ΔDEF

Answer:
Step-by-step explanation:
AC² + AP² = PC²
AC² + 5² = 13²
AC = 12
radius = AC/2 = 6
Answer:
- 2nd quadrant: 120°
- 3rd quadrant: 240°
Step-by-step explanation:
Dividing by cos(x)², you get
... (sin(x)/cos(x))² = 3
... tan(x)² = 3
... tan(x) = ±√3
... x = arctan(±√3) = ±60° + k·180° for any integer k
In the 2nd quadrant, ...
... x = 180° -60° = 120°
In the 3rd quadrant, ...
... x = 180° +60° = 240°

A graphing calculator can help you find or check answers. In most cases it works well to rewrite the equation to a form that is equal to zero. Here, we have subtracted 3cos(x)² from both sides of the equation.
Answer:
√15/3
Step-by-step explanation:
x² - y² =√5
(x +y)*(x -y) = √5
(x +y) * √3 = √5
x+y = √5 / √3
x +y = √5*√3 / √3*√3
x +y = √15/3
